T all whom t may concern.'

Be it known that I, Grenen E. MARLATT, a citizen of the United States,-residing at Pasadena, in the county of Los Angeles and State ofy California, have invented a new and useful Improvement in Type-Casting Mechanisms for Linotype-Machines, of which the 'following is a speciiication.

My `invention relates t0 type casting mechanism for linotypemachines and. more particularly to the slug ejecting mechanism associated with said mechanism, and hasefor its object the provision of a universal means for ejecting the slugs from the mold after the casting operation;.a more efficient and automatic arrangement of some of the closely i related parts ofthe casting mechanism; reducing the amount of manual effort required for the operation of said mechanism toa minimum; and a. generalsimplifyingy of the elements of the type casting mechanism.

' Other objects may appear in thel subjoined detailed description vof my device as illustrated in the accompanying drawings yin which Figure 1 is a perspective view of y universal ejector; Fig. 2 is a side elevation of one of the multiple ejector members with the corresponding sizes of the other members indicated in dotted lines; Fig. 3 is A an end elevation of Fig. 1, partly broken away; Fig. l is a sectional elevation on the line 4-l, Fig.. 1, of thcI ejector base andis a perspective of the same; j, Fig. 6 is a sectional elevation on the line.

Similar .characters of reference Windicate `the same parts throughout thejspecifications vand the several views `of the drawings. Y In my mechanism, as hereinafter fdc-- scribed, many changes ofV minorimportance "an arbor,

haveV been made in the gene-ral outlines and: l

relationship ot someof the old parts typical of'linotype machines, in order to adapt "the -machine to use in connection therewith, and

mold disk and drivingpinion, with the latter rplaced at the bottom oftheformer on the vertical center line. j l

My universal and ,variable ej ecting mechanisml is deslgfied to simplify the operation of a Slug casting machine, to economize in time and labor and to generally facilitate the'ejecti'on of the slugs from the molds, and I providea plurality of ejector blades. of variouswidths mounted n setsiof four, in

adjustable sired blade. in' alinement with the casting slot of the mold for the ejecting operation.

The vbase 107. is rigidly mounted ou the frame of the machine and has a lateral groove` 108 about centrally disposed betweenthe ends with Vthe countergroove 109 on each side thereof; and at the bottom of the former. The ejector carriage 110 has a floor 111 and two upwardly extending sides 112, the upper. ends of which are provided with theforward extension 113 and the vrear extension 11-1 the former. The carriage is adapted to lslide laterally in the central groove 108 and Y the floor 111 has theextensions 115 adapted to engagev and slide in .the countergrooves 109; the side of the floor having the rack 116 extending therefrom and provided with vthe grooves 117 adaptedto be engaged b v the threads on thev worm .118 which is revolubly mounted in the base 107, ycentrally with and below the carriage 110 inthe bore 119 and on the shaft 120which is provided with recesses 123, in eacho which isx mounted on anv arbor 124, Vone of the multiple ejectors 125 having the blades 126, the lower ,edge

127 of each of the blades on the ejectors 'being an Vequal distance from the center, and vthelower edges of. opposite blades being fParallel l I v For convenience in assembling.. each of the 4slides..122 have, thev plates 12S secured thereto by the screws129, the plates serving Hto close one side of the recessesv 123, and the base "10,7, y isprovided with la Vlongitudinal which is slightly longer than land both laterally and'pivotallyw in order tor readilyplace rany yde-` groove at the length of the base, in the groove 108 132 adapted to register with the bottom ofA the groove 130. rl`he groove 130 is adapted to aline vertically with the casting Slot 133 in the mold and the ejector slides are adapted to Slide forward in this groove in an ejecting operation, as shown in Fig. 1.

The blades 126 are so arranged in position on the ejectors as to give an ascending scale of widths of the slugs both around their center and laterally across the carriage, the width of the blade corresponding inl all cases to the length ofthe slugs that are cast and ejected by a particular blade, and the number of blades and the arrangement shown covers the entire range of sizes required for lthe ejection of all lengths of slugs. l make one of the blades 1311 removable so that blades of irregular or narrower widths may be substituted therefor, the ejector being provided with a slot 135 and the blade being secured in the slot and prevented from removal therefrom by a pin 136 secured in the inner end of the blade and adapted'to engage an annular groove 137 in the plate 128, the pin 136 being secured also in a flange 138 adjacent to the blade. The pin 136 in its relation with the groove 137 locks the blade 13a against removal, and the outlet 137 to the groove 137 serves to permit the removal of the blade.

rlhe rear ends of the slides 122 are provided with a circular groove 139 with the edges beveled as in other machines the end of the ejector lever 140 being adapted to seat in a desired one of the slides for ejecting a slug from the mold, and an arm 141 having a groove 142 in which the lever by the top plate 143, is secured to the frame of the machine as a steadying means for the arm. The slides 122 are placed in operative relation with the lever 1&0 by moving them laterally with regard thereto and causing the engagement of the lever end with the groove 139. '.The ejector vslide hasa resilient brace rod 144 mounted upon it which is pivoted to the top edge of the slide 122 on a pin 145; the rod lila'also has a rear lug 146 adapted to engage a stop pin 1l7v secured in the slide to limit the inward movement of the brace rod, a spring 1/l7f being secured at one end to the upper edge of the slide and at the other end looped around a pink 1117 for holding the front end 1-'18 of the rod resiliently in engagement with the blades 126, and this front end is tapered toward the front so that the front-edge will enter and engage the edge of the perforation 149 in the blades and thus prevent a backward movement thereof, but backwardly from the end' to permit aforward movement of the blades around their axis.

vprovided on the inside of 1110 is held @ne of the bracerods lef-1 is provided for Fig. 1 to avoid obscuring `other parts.

Each of the arbors 12st has a central square perforation 12st and in these perforations the rod 150 which has the squared end 150 isadapted to slide laterally against `the tension of the spring 151 when forced in by the operator, for turning` the `ejectors and placing three of the blades 126 in selective position. The rod 150 is slidable also in the column 152 ofthe frame of the machine, is the column with a iianged collar 153 secured tothe rod 150 by the screws 154 and Ahas four equally spaced perforations concentrically arranged around its face adapted to receive the `pin 155 which is secured in the column. Thus the collar 153 may be radiallyy adjusted by forcing it off of the pin 155 and turning the rod 150 so that. another of the perfor-ations may be engaged by the pin, the sets of blades being thus turned by quarters.

rlfhe outer end of the rod able crank 156 tofacilitate the turning thereof and also a collar 157 which is secured to the rod-by a screw 153,between which collar and the column, the spring 151 is adapted to becompressed. wWhen the rod is forced into a position in the ejectors and the latter areY turned, the rod may be thus restored by the spring. As. a means `for visibly indicating the proper position of therrod 150 for each of the blades 126, l provide a pin y160 which is secured to the inner side 112 ,of the carriage, extends into ythe column 152 and carriesan indeXshield 161which covers the rod 150 and has a suitable perforation 162 'through which may be seen a number representing a certain blade, the numbers being marked on the rod 150.

rlhe worm shaft 120 is also revolubly mounted in the ycolumn 152 of the machine, is provided on its outer end with a crank 163 made slidable thereon by means of a screw -16-1- in a slot 165 in the shaft 120, and has an 163, the rod 167 serving to lock the worm' shaft against rotary movement.L

l `When it is desired to place one of the slides 122 in operative position, ythe crank 163 may be pulled outwardly and the rod 167 released from its seat in the column 152, the shaft 120 may then be turned in the proper direction, and by the engagement of the worm on this shaft with the rack 116, the carriage-may be moved liuerally in the .base 107 until a desired slide is in alinement 150 has a suit-V with the casting slot of the mold and the desired number on the rod 150- is visible through the opening in the shield 161, when the crank may be released and the spring 168 will force the rod 167 back into its seat in the column 152.

The block 168` at the rearof the .base 107 is secured in theframe of the machine, and between it andthe base is another block 169 which has an upper projection `170 adapted to limit the backward l movement of the slides 122 and which is shortenough to provide an opening 171 between the `block'l'68 and the base 107 one or more springs-172` being suitably mounted beneath the block 169 for iesiliently holding the block in pof sit-ion. The purpose of the springs 172 and the construction of the'rear of thebase,

. just described, is to facilitate4 the removal of 184 for advancing and retractingthe mold Y Each end of the frame 178 has one ofthe centrally positioned bearings 175 and a pair of the bearings 176 arranged on opposite sides of the center of the auxiliary frame. The rods 177 are slidably mounted in the bearings 176, extend outwardly from each end of the frame and have on their front `end the mold disk support 178 which has its lower end 179 secured to the rods 177 andV its upper bearing 180 adapted to serve as a mounting for the mold disk.

The cross head 181 is secured to the rods 177 near the rear of the frame 1'731and has an upwardly extending yoke 182 adapted to engage the roller 183 on the mold cam lever disk in the usual manner. The mold turning pinion 2 is fixed to the shaft 4 which is frame 178 and is comp'osedof two parts `independent of each'otheig-as shown inFig.` f 11, the forward portionl Z1- being slidable in l the rear portion 185. Ea'chof the portions and 1850il this shaft is providedjw'ith a jaw clutch member-186 secured iny position Vthereon. by i 4 otherwise, the jaws of the-two clutch memmeans of a 'set screw 187,-'or
